WPRO-AM reports that someone broke into a donation collection box in the elephant and giraffe pavilion sometime between Nov. 28 and Tuesday. Zoo officials say the box typically brings in between $100 and $200 a week.

The station reports the money is used to buy toys and other enriching material for the zoo's animals. A spokeswoman says the zoo is saddened by the incident.

The zoo has rebuilt the collection box in an effort to prevent future thefts.
